List: Similarities and differences between flu and COVID-19​

Flu Shots Covid

The flu season is now underway and with some of the symptoms of flu and COVID-19 being so similar, it may be hard to tell the difference between them based on symptoms alone.

The CDC has compiled a list of how the viruses compare to one another.

Similarities between COVID-19 and flu:

  • Fever or feeling feverish/chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue (tiredness)
  • Sore throat
  • Runny or stuffy nose
  • Muscle pain or body aches
  • Headache
  • Some people may have vomiting and diarrhea, though this is more common in children than adults


  • Symptoms: COVID-19, unlike the flu, may include change in or loss of taste or smell.
  • Exposure and Infection: Symptoms will typically, develop 5 days after being infected, but symptoms can appear as early as 2 days after infection or as late as 14 days after infection, and the time range can vary. Whereas a person develops flu symptoms anywhere from 1 to 4 days after infection.
  • Spread: While COVID-19 and flu viruses are thought to spread in similar ways, COVID-19 is more contagious among certain populations and age groups than flu. 
  • Vaccine: There are multiple FDA-licensee influenza vaccines to protect against the strain scientists anticipate will circulate each year. Currently there is no vaccine to prevent COVID-19, while there are vaccine trials in the works.

  1. They have forgotten that the death rate is similar but the difference is that the elderly are the highest risk, whereas influenza kills infants. Is it a coincidence during pre-Covid, that anyone could walk into an ER room, doctor, or clinic with ANY known disease with any symptom and not wear a mask?
